Benefits of technology

[0029]Embodiments of the present invention provide for an OLED display having a pixel defining layer that can be formed to have a sufficiently large thickness to protect the pixels and reduce unwanted capacitance while maintaining film uniformity of a first medium layer. Accordingly, the pixels are not pressed (for example, directly pre...

Problems solved by technology

For example, when an encapsulating substrate is pressed toward pixels in a structure having the encapsulating substrate provided on the organic light emission layer, if the thickness of the pixel defining layer is too small, the pixels may be p...

Embodiment Construction

[0038]Aspects and features of the present invention and methods of accomplishing the same may be understood more readily by reference to the following detailed description of exemplary embodiments and the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided to more fully convey concepts of the present invention to those skilled in the art. The scope of the present invention is defined by the appended claims, and their equivalents.

[0039]When an element or layer is referred to as being “on” another element or layer, it can be directly on the other element or layer, or intervening elements or layers may be present. Like numbers refer to like elements throughout. Although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers, and / or sections, these elements, componen...

Abstract

An organic light emitting diode (OLED) display is provided. The OLED display includes: a substrate; a first electrode on the substrate; a first pixel defining layer exposing at least a portion of the first electrode; a medium layer on the first pixel defining layer and the first electrode, the medium layer including a first region and a second region; a second pixel defining layer overlapping the first pixel defining layer with the first region therebetween; a light emission layer overlapping the first electrode with the first region therebetween; and a second electrode covering the second pixel defining layer and the light emission layer.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Korean Patent Application No. 10-2012-0099777, filed on Sep. 10, 2012 in the Korean Intellectual Property Office, the entire content of which is incorporated herein by reference.BACKGROUND[0002]1. Field[0003]Aspects of embodiments of the present invention relate to an organic light emitting diode (OLED) display and a method of fabricating the same.[0004]2. Description of the Related Art[0005]An OLED display is a self-emissive display device that displays images by exciting an emissive organic material to emit light. The OLED display includes an anode (i.e., a hole injection electrode), a cathode (i.e., an electron injection electrode), and an organic light emission layer interposed therebetween. When the holes and the electrons are injected into the light emission layer, they recombine to form excitons, which emit light when they change from an excited state to a ground state.[0006]The...
